Area of the hallway = 90 * 7 = 630 ft^2
Since each square foot needs a 1/2 ounce of solution to find the amount of fluid we need we multiply the area by 1/2.
= 630 * 1/2
= <u>315</u> fluid ounces (answer).
Your question is really hard to read, but I'll give my best to give you an appropriate answer.
Generally, a sample which best represents the population would usually be one which makes it equally likely for everyone to be included into that sample.
<span>
observing every person walking down Main Street at 5 p.m. one evening to determine the percentage of people who wear glasses
</span>
and measuring the heights of every fiftieth person on the school roster to determine the <span>average heights of the boys in the school calling every third person on the soccer</span><span> </span>
Are surely two. It is questionable if any of the other ones are really randomized and represent the population fairy well or not.
Using cosine, we can find the hypotenuse by using the formula below;
hypotenuse = adjacent / cos ∅
<h3 /><h3 /><h3>Trigonometric ratios:</h3>
- Trigonometric ratios are ratios of sides of a right angled triangle.
- The simplest ratios are cosine, sine and tangent.
Using cosine, the hypotenuse side can be solved as follows:
cosine ∅ = adjacent / hypotenuse
cross multiply
hypotenuse cos ∅ = adjacent
divide both sides by cos ∅
hypotenuse cos ∅ / cos ∅ = adjacent / cos ∅
Therefore,
hypotenuse = adjacent / cos ∅
